How to get and set Lagom Kafka Consumer configuration?

I’m using Lagom 1.6 and implements a topic.subscribe in a microservice implementation.
I would like to change the commit batching-size of this consumer but it doesn’t seems to change something. I tried to add this to my application.conf: = 1 = 1 = 100 millis

according to Lagom documentation:

Also I really need to print all parameters in order to know what parameters are used but I don’t know how to do it.


You can check if your configuration are being loaded if you debug your dependency inject configuration at the running time. Try this

class MySubcriber(config: Configuration) {


def setUpMySubcriberConfigs() {
   val lookAtMyConfigs = config.get[Configuration]("")
  // debug point


Is not the smartest way to do that but you ill be able to see if the configs are loaded
